MCHM is one of tens of thousands of chemicals exempt from testing under the federal Toxic Substances Control Act because they were already in use when the law was approved in 1976. A fact sheet of available data on the chemical says there is no specific information about its toxic effects on humans. Its chances of causing cancer and its effects on reproductive health are unknown, according to the document and the CDC.

 

What are those TENS OF THOUSANDS OF CHEMICALS ? We’re pretty good at this, and we cannot find the list!
